Re: pyROOT on Mac OS X Snow Leopard

Hi,

ROOT will have been built for 64 bit architecture, I bet. On my machine, I have the following:

Unknown-00-21-e9-e2-86-6e:~ jamesjackson$ file `which root` /usr/local/bin/root: Mach-O 64-bit executable x86_64

Unknown-00-21-e9-e2-86-6e:~ jamesjackson$ file `which python`

/usr/bin/python: Mach-O universal binary with 2 architectures
/usr/bin/python (for architecture ppc7400):	Mach-O executable ppc
/usr/bin/python (for architecture i386):	Mach-O executable i386

One could possibly force ROOT to build for 32 bit, or re-build python for 64 bit. I suspect the former is easier...

Regards,
James.
